Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 51,754,307, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 51,754,307 | |
| -1 | -51,754,307 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,754,307.
Example:
1 x 51,754,307 = 51,754,307
and
-1 x -51,754,307 = 51,754,307
Notice both answers equal 51,754,307
With that explanation out of the way, let's continue. Next, we take the number 51,754,307 and divide it by 2:
51,754,307 ÷ 2 = 25,877,153.5
If the quotient is a whole number, then 2 and 25,877,153.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 51,754,307 | |
| -1 | -51,754,307 |
Now, we try dividing 51,754,307 by 3:
51,754,307 ÷ 3 = 17,251,435.6667
If the quotient is a whole number, then 3 and 17,251,435.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 51,754,307 | |
| -1 | -51,754,307 |
Let's try dividing by 4:
51,754,307 ÷ 4 = 12,938,576.75
If the quotient is a whole number, then 4 and 12,938,576.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 51,754,307 | |
| -1 | 51,754,307 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 103 | 187 | 1,133 | 1,751 | 2,687 | 19,261 | 29,557 | 45,679 | 276,761 | 502,469 | 3,044,371 | 4,704,937 | 51,754,307 |
| -1 | -11 | -17 | -103 | -187 | -1,133 | -1,751 | -2,687 | -19,261 | -29,557 | -45,679 | -276,761 | -502,469 | -3,044,371 | -4,704,937 | -51,754,307 |
